On September 29, 2021 at 18:58 UTC, a magnitude 3.7 shallow crustal earthquake struck 41 km NNE of Punta Cana, Dominican Republic, at a depth of 9.0 km and coordinates 18.9375°, -68.2785°.
Physical scale: An earthquake of magnitude 3.7 releases seismic energy equivalent to roughly 4.8 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 205 m — a useful intuition for the size of the slip patch on the fault.
